Does anyone know what will make a Integra get terrible gas mileage ? I have a 1990 Acura Integra DB1 with LS/VTEC all stock no bolt ons on it and it has always gave me terrible gas mileage. I lately just changed the fuel filter and it now gives me a lil better gas mileage but it usually gives me 230 miles per tank in the city when I know its supposed to be giving me more than that. Anyone know what can cause my car to give bad gas mileage ?

Miles per tank is a useless measurement. Get actual MPG, over the course of multiple tanks, and provide us with an average so we actually have a useful number to work with.

You can't write "LS/VTEC" and "stock" in the same sentence and have it mean anything.

How was the car tuned? What's the AF under partial throttle cruise conditions? Condition of O2 sensors?

Alignment plays a large role in mileage too.

btw 238 is not bad. do u use vtec often.

Does engine start as easily when warm, [before engine has a chance to cool down after turning ign. off] as when it is cold, [first thing in the morning]?

If not, you have a problem with the ECT sensor and your running rich.

I agree you need to do a proper MPG test to get an accurate account of MPG.

Fill tank to the top, set trip meter, drive untill you need gas, when gauge reads 1/2 tank will work, record miles driven, fill to top again, record fuel put in, do that a few times add up miles driven and fuel put in, divide and you have an accurate MPG. 94

236 miles is 377.6 km and i would usually average around 400 a tank when my gsr was na give or take 25 k depending on hhowi drove it. once i only got 320 out of a tank so i'd say your not too far off sorry for km but im metric lol.

There's nothing to discuss until you are tuned.
